    Starship Delays May Affect NASA’s Moon Landing Timeline

    Why in the News

    A report by NASA’s Inspector General warns that delays in SpaceX Starship could affect the timeline of the Artemis Program, which aims to land humans on the Moon before 2030.

    Background: Artemis Moon Mission

    • NASA is working with private companies like SpaceX and Blue Origin
    • The Artemis programme aims to establish sustainable human missions to the Moon and eventually support missions to Mars.
    • Originally, the Moon landing under Artemis III was targeted for 2024, but delays have pushed the timeline to around 2028 or later.

    Why It Is Difficult

    • Starship uses liquid methane and liquid oxygen as fuel. These must be stored at cryogenic temperatures below −150°C.
    • The system must perform multiple docking and fuel transfers in Low Earth Orbit (LEO).
    • LEO already has heavy satellite traffic, increasing operational risk.

This is so because the attraction of Earth (a) does not exist at such a distance. (b) is neutralized by the attraction of the moon. (c) provides the necessary speed for its steady motion. (d) provides the necessary acceleration for its motion.
  • Euthanasia Mercy Killing

    Supreme Court Upholds Right to Die with Dignity

    Why in the News

    The Supreme Court of India allowed withdrawal of life-sustaining treatment for Harish Rana, reaffirming the right to die with dignity under Article 21 of the Constitution of India. The judgment was delivered by Justices J. B. Pardiwala and K. V. Viswanathan.

    Key Features of the Judgment

    1. Withdrawal of Life Support Allowed

    • The Court permitted withdrawal of Clinically Assisted Nutrition and Hydration (CANH) for a patient in a Persistent Vegetative State (PVS).
    • This allows the natural process of death rather than artificially prolonging life.

    2. Replacement of the Term “Passive Euthanasia”

    • The Court clarified terminology: Active euthanasia remains illegal in India.
      • The earlier term passive euthanasia will now be called “withholding or withdrawal of medical treatment.”

    3. Structured Medical Process Required

    Withdrawal of life support must not be a single act. It must involve:

    • A structured palliative care plan
    • Medical assessment of whether treatment is futile or non-beneficial
    • Ensuring the patient does not suffer unnecessary pain.

    4. Medical Board Review

    • Primary and secondary medical boards must examine such cases.
    • If both boards approve withdrawal, hospitals must inform the Judicial Magistrate of First Class.

    5. Focus on Patient’s Best Interest

    The Court clarified the test:

    • Not whether it is better for the patient to die
    • But whether it is better not to artificially prolong life through futile treatment.

    Legal Background

    • The ruling implements guidelines laid down in the landmark case: Common Cause v. Union of India (2018)
    • That case recognised:
      • Right to die with dignity
      • Living wills or advance medical directives

    Court’s Recommendations

    The Court urged the Government of India to enact a specific law governing withdrawal of life support and end-of-life care.

    Significance

    • Strengthens the interpretation of Article 21 to include dignified death.
    • Clarifies procedures for end-of-life medical decisions.
    • Balances medical ethics, patient autonomy, and constitutional rights.

  • Finance Commission – Issues related to devolution of resources

    41% illusion: a quiet re-engineering of India’s fiscal landscape

    Why in the News?

    The Union government accepted the Sixteenth Finance Commission’s recommendation to retain States’ share in the divisible pool at 41%. However, the effective share of States has declined because the divisible pool itself has shrunk relative to gross tax revenues. Simultaneously, the Union has increased reliance on cesses and surcharges that are not shareable with States, while discontinuing several revenue deficits and state-specific grants. The result is a structural shift toward greater fiscal centralisation, even though the headline devolution figure remains unchanged.

    Why is the “41% devolution” being called an illusion?

    1. Headline Continuity vs Real Decline: Retention of 41% vertical devolution creates an impression of continuity. However, the divisible pool is not the same as gross tax revenue, reducing the effective share transferred to States.
    2. Rise of Cesses and Surcharges: Cesses and surcharges are retained entirely by the Union and excluded from the divisible pool. Their growing share reduces the amount available for distribution to States.
    3. Shrinking Shareable Pool: The divisible pool averaged 89.2% of gross tax revenue during FC-XIII, declined to 82.1% during FC-XIV, and further to 78.3% during FC-XV.
    4. Effective Devolution: When calculated as a share of total Union tax revenue, the States effectively receive about 41% of a shrinking pool, lowering the real transfer.

    How has the divisible pool evolved over time?

    1. FC-XIII Period (2010-15): Divisible pool averaged around 89.2% of gross tax revenue, ensuring larger transfers to States.
    2. FC-XIV Period (2015-20): States’ share increased to 42%, but the divisible pool reduced to 82.1% of gross tax revenue.
    3. FC-XV Period (2020-25): States’ share reduced to 41%, while the divisible pool further declined to 78.3%.
    4. Trend: Declining shareable revenue base despite stable devolution percentage.

    Why are cesses and surcharges central to the fiscal federal debate?

    1. Exclusion from Divisible Pool: Cesses and surcharges are not shared with States under Article 270.
    2. Growing Fiscal Instrument: The Union increasingly uses cesses and surcharges to finance schemes, bypassing revenue sharing.
    3. Impact on State Finances: Rising non-shareable revenues reduce States’ fiscal autonomy.
    4. Example: Education cess, infrastructure cess, and other targeted levies contribute to Union revenues but do not increase States’ transfers.

    What structural changes in Finance Commission transfers affect States?

    1. Discontinuation of Revenue Deficit Grants: FC-XVI proposes removal of revenue deficit grants, previously used to support fiscally weaker States.
    2. End of State-specific Grants: Instruments providing targeted relief for State fiscal stress have been discontinued.
    3. Shift toward Conditional Grants: Transfers increasingly depend on States’ compliance with Central monitoring requirements.
    4. Change in Devolution Formula: Criteria such as tax and fiscal effort have been removed, while contribution to GDP has been introduced.

    How does the new horizontal devolution formula affect States?

    1. Income Distance (42.5% weight): Continues to prioritise poorer States with lower per-capita income.
    2. Population (17.5% weight): Based on 2011 Census, increasing weight relative to earlier formulas.
    3. Demographic Performance (10% weight): Rewards States with better population control outcomes.
    4. Area (10%) and Forest Cover (10%): Recognises geographical and ecological constraints.
    5. Contribution to GDP (10% new criterion): Rewards States contributing more to national output.

    What fiscal stresses among States shaped the Commission’s approach?

    1. Punjab: Debt-to-GSDP ratio around 42.9% in 2023-24; revenue deficit estimated at 3.7% of GSDP.
    2. Rajasthan: Outstanding liabilities around 37.9% of GSDP.
    3. Andhra Pradesh: Debt levels approximately 34.6% of GSDP.
    4. Observation: States increasingly borrow to finance salaries and service existing debt rather than build capital assets.

    Why is the shift toward conditional transfers significant?

    1. Performance-linked Transfers: Local body grants divided into basic and performance components.
    2. Conditionality: Access to funds linked to timely audits, compliance with Central databases, and performance benchmarks.
    3. Governance Impact: States with weaker administrative capacity may receive lower actual transfers despite formal entitlement.

    What broader implications does this have for fiscal federalism?

    1. Centralisation of Fiscal Power: Increasing Union control over tax revenue and grants.
    2. Reduced Fiscal Autonomy: States depend more on conditional transfers rather than formula-based devolution.
    3. Structural Imbalance: Growing gap between State expenditure responsibilities and fiscal resources.
    4. Long-term Concern: Persistent asymmetry may weaken cooperative federalism.

    Conclusion

    The retention of the 41% devolution figure conceals deeper structural changes in India’s fiscal architecture. The shrinking divisible pool, rising use of cesses and surcharges, and growing conditionality of grants indicate a gradual centralisation of fiscal authority. Sustaining cooperative federalism will require greater transparency in tax sharing and a stronger balance between Union and State fiscal powers.

    PYQ Relevance

    [UPSC 2021] How have the recommendations of the 14th Finance Commission of India enabled the states to improve their fiscal position?

    Linkage: The PYQ Tests understanding of Finance Commission’s role in fiscal federalism and tax devolution between Centre and States. The issue of retaining 41% devolution while the divisible pool shrinks due to rising cesses and surcharges highlights emerging tensions in Centre-State fiscal relations and effective resource transfers.

    India Looks to New Gas Sources to Ease LPG Shortage

    Why in the News

    Amid supply disruptions caused by the West Asia conflict, officials say India is turning to new sources of natural gas such as the United States and Norway to address the current shortage of cooking gas (LPG).

    Key Developments

    • India is facing a temporary shortage of LPG and LNG supplies.
    • The government has increased domestic LPG production by about 10%.
    • Oil refineries have been directed to prioritise propane and butane for LPG production.
      • This directive was issued by the Ministry of Petroleum and Natural Gas.

    Diversifying Gas Imports

    • India is exploring imports from: United States and Norway
    • Earlier, a major share of LNG imports came from Qatar.

    Price Changes

    • Earlier LNG price: $6–8 per MMBtu
    • Current price: around $15 per MMBtu
    • At higher prices, imports from distant suppliers become economically viable despite longer shipping distances.

    Supply Challenges

    • Shipping LNG from the U.S. or Norway can take about two months.
    • This may cause a short-term supply gap before new cargoes arrive.
    • However, officials expect the shortage to be temporary.

    Government Priority

    • The government has prioritised domestic LPG supply for households over commercial users.
    • To address concerns of hotels and restaurants, a committee of oil marketing companies (OMCs) has been set up to review requests for commercial LPG supplies.

    Key Terms

    • LPG (Liquefied Petroleum Gas)
      • Mainly composed of propane and butane.
      • Used widely as cooking fuel in households.
    • LNG (Liquefied Natural Gas): Natural gas (mostly methane) cooled to −160°C to transport it in liquid form.

    Significance for India

    • India imports a large share of its energy requirements.
    • Disruptions in West Asia affect fuel supply, prices, and energy security.
    • Diversifying suppliers helps reduce dependence on a single region.

  • Climate Change Impact on India and World – International Reports, Key Observations, etc.

    Behind an early summer is a lack of winter rains

    Why in the News?

    An unusual surge in temperatures across north and north-western India during February-March has raised concerns about shifting seasonal patterns. Several regions recorded temperatures 8-13°C above normal, bringing heat-wave-like conditions weeks before the usual onset of summer. The phenomenon has been linked to deficient winter rainfall and weak Western Disturbances, which are critical for regulating winter climate in north India. 

    Why is India witnessing unusually high temperatures early this year?

    1. Temperature Anomaly: Several regions recorded temperatures 8-13°C above normal, reaching heat-wave-like conditions in February-March.
    2. Early Heat Conditions: Warm weather replaced cool winter days earlier than usual in northern and western India.
    3. Rare Occurrence: A similar situation occurred three years ago, but such an early onset of summer remains relatively uncommon.
    4. Regional Evidence:
      1. Shimla: 25.3°C (March 2026, highest recorded till March 8).
      2. Pahalgam: 22.7°C.
      3. Gulmarg: 17.2°C.
      4. Srinagar: 24.7°C.

    Climatological Significance: Heat waves are generally uncommon in high-altitude regions such as Shimla in March.

    How did weak Western Disturbances influence the winter climate?

    1. Western Disturbances: East-moving rain-bearing weather systems originating beyond Iran and drawing moisture from the Mediterranean Sea and other water bodies.
    2. Seasonal Importance: These systems normally bring winter rainfall and snowfall across northern India.
    3. Deficiency Since November 2025: Reduced frequency and intensity of Western Disturbances led to lower winter precipitation.
    4. IMD Observation: Meteorologists noted lack of wind convergence between westerly and easterly winds, reducing moisture transport into north and central India.
    5. Temperature Regulation: Winter precipitation normally moderates temperatures by maintaining soil moisture and atmospheric cooling.

    Why was the winter of 2026 considered unusually dry?

    1. Rainfall Deficit: All-India rainfall during January-February was only 16 mm, which is 60% below normal.
    2. Historical Context: February 2026 became the third driest February since 1901.
    3. Snowfall Decline: Both snowfall and rainfall remained subdued across Himalayan regions.
    4. Meteorological Cause: Persistent lack of favourable weather systems during winter months.

    How does a dry winter accelerate the onset of summer?

    1. Soil Moisture Deficit: Reduced rainfall leaves soil dry and unable to moderate temperature increases.
    2. Evaporation Mechanism: Moist soils normally evaporate moisture before heating up, delaying temperature rise.
    3. Rapid Surface Heating: Dry soils heat faster, increasing land surface temperature and accelerating summer conditions.
    4. Climate Feedback: Dry land conditions amplify regional warming and heat stress.

    What are the implications for agriculture and water resources?

    1. Impact on Rabi Crops: Sudden temperature spikes affect mustard, wheat, gram, groundnut, sesame, sorghum, and sunflower.
    2. Horticulture Stress: Crops such as potatoes and apples may suffer due to heat stress.
    3. Irrigation Demand: Farmers have been advised to increase irrigation frequency to maintain soil moisture.
    4. Water Resource Pressure: Increased irrigation demand may strain local groundwater and water reserves.

    What do temperature records indicate about changing climatic patterns?

    1. Temperature Extremes: High temperatures in Himalayan regions during early March indicate increasing climate variability.
    2. Comparison with Past Years:
      1. 2026: Shimla 25.3°C, Pahalgam 22.7°C, Gulmarg 17.2°C, Srinagar 24.7°C.
      2. 2025: Shimla 24.4°C, Pahalgam 20.4°C.
      3. 2024: Shimla 24.8°C.
    3. Climate Signal: Frequent anomalies suggest greater unpredictability in seasonal transitions.

    Conclusion

    The early onset of summer in India highlights the critical role of winter rainfall and Western Disturbances in maintaining seasonal balance. Reduced precipitation has accelerated land heating and increased agricultural vulnerability. Strengthening climate monitoring, improving irrigation management, and integrating seasonal forecasting into agricultural planning are essential to mitigate the impacts of such climatic anomalies.

    FSI Stops AI-Based Deforestation Alerts to States

    Why in the News

    The Forest Survey of India (FSI) has stopped issuing fortnightly deforestation alerts through its AI-based Anavaran Deforestation Alert System. The portal has not been updated since November 2025.

    What was the Anavaran System?

    • An AI and satellite-based monitoring system launched in January 2024.
    • Provided deforestation alerts every 15 days to states.
    • Alerts included precise geographic coordinates where forest cover loss was detected.

    Purpose:

    • Enable quick field inspections by forest officials.
    • Improve near-real-time monitoring of deforestation.

    Technology Used

    The system used remote sensing and machine learning:

    • Google Earth Engine
    • Sentinel-2
    • Sentinel-1

    Features:

    • Optical satellite imagery (Sentinel-2).
    • Synthetic Aperture Radar (SAR) data from Sentinel-1 for cloudy or monsoon conditions.
    • Machine learning algorithms compared before-and-after images to detect forest loss.

    Performance of the System

    • 12,351 alerts issued between Jan 2024 and Oct 2025.
    • Average alerts per month: 561
    • Alerts increased to 1,028 per month during Nov–March, when deforestation peaks.

    Why Alerts Were Stopped

    • According to FSI officials:
      • The system was only a pilot project.
      • The government is currently reviewing feedback from states on its usefulness.
      • Active monitoring reportedly stopped in January 2026.

    Comparison with Global Systems

    • The system was considered similar to Terra‑I, used in countries like Peru. However, Anavaran had higher spatial resolution:
      • 10–20 metre resolution (Sentinel satellites)
      • Terra-I: 250 metre resolution

    Other Forest Monitoring Systems in India

    • Van Agni Portal
    • Fire alerts using satellite data have been operational since 2004.
